Which of the following statements is true?
question 19 options:
carbohydrates contain more energy that lipids because their bonds release more energy when broken.
lipids contain more energy that carbohydrates because they contain more carbon to hydrogen bonds to release energy when broken.
fats contain half the amount of energy than carbohydrates because they have less bonds.

Lipids contain more energy that carbohydrates because they contain more carbon to hydrogen bonds to release energy when broken.

A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.

Ecological footprint is determined by measuring carbon dioxide emissions for a given region.
